I just thought it'd be cool if there was an app that you could point to a web app, such as a game, or the new yellowpages one, and basically download the entire site (like you can with a normal browser, for offline viewing) and somehow it'd create it's own little icon that you could then launch whenever you want... for the times when a data or wifi connection isn't available...
